Sounds pretty normal--I used to have to get up and pump some if dd went more than an hour past what my body was used to because I was so uncomfortable I couldn't sleep anyway. your body will adjust, and if you don't have to pump, it will probably happen even faster because by pumping, you actually encourage your body to keep up the supply to that level. I always tried to only take off enough to get comfortable again. Nothing like waking up with boobs as hard as sharp rocks!!!!!!!
